k. Anti-Condensation Heating Protection: Enhance performance with our anti-condensation heating protection. Selectively activate the heating resistor based on electrical cavity temperature to prevent condensation, maintaining optimal performance and extending the lifespan of the valve actuator.
2.7 Local Control
AUKEMA actuators are equipped with two innovative, non-intrusive magnetic control knobs. The mode knob offers three distinct positions: 'local', 'remote', and 'stop', allowing for precise control. The operation knob provides two options: 'open' and 'close'. Set the mode knob to 'local', and simply adjust the operation knob to maneuver the actuator in your desired direction, whether opening or closing. Choose from two local control modes: 'jog' for precise movements or 'hold' for consistent operation, ensuring adaptability and control.
2.8 Remote Control
Effortlessly control the actuator remotely by integrating DCS or PLC systems via a hard-wired cable connection. Manage operations with simplicity through switch quantity for manual control or current quantity for automatic control, offering flexibility and ease of remote operations.

Additionally, you have the option to select remote analog quantity feedback of torque, offering enhanced operational insights.
2.9 ESD Control
In times of critical need, our ESD signal takes precedence, overriding any local or remote signals (as per predefined parameter settings). This allows the actuator to decisively close or open the valve, ensuring optimal protection. Choose from 'close the valve', 'open the valve', or 'hold position' for your ESD action, tailored to your safety requirements.
2.10 Interlock Control
Tailored for the most exacting environments, our actuator is engineered for conditional control, meeting the demands of your rigorous applications with precision.
In this sophisticated mode, operation is predicated upon two independent signals. For instance, when both a remote close input and a close interlock input are received simultaneously, the actuator will execute a valve closure. Should only one signal be received, or if one is lost, the actuator will hold its position or halt, safeguarding against potential failures. For applications necessitating ESD, a dedicated ESD input is provided, taking precedence over other control signals, thereby ensuring paramount safety by disregarding any concurrent signals.
